Our club has 20 members, 10 boys and 10 girls. In how many ways can we choose a president and a vice-president if they must be of different gender?

AND...

 

No two students in Mrs. Vale's 26-student mathematics class have the same two initials. Each student's first name and last name begin with the same letter. If the letter ``Y'' is considered a vowel, what is the probability of randomly picking a student whose initials are vowels? Express your answer as a common fraction.

Your answer is right but your logic is wrong.

10 ways to pick the girl, 10 ways to pick the boy But the girl can be president or vise, once the girls' position is fixed so is the boys so that is 2 ways

 

answer  10*10*2 = 200
